Re: [webbeans-dev] Replacement pattern for Manager.getInstanceByType

I don't understand what you would be wanting to do this yourself all over the place. Why on earth are you going to be performing typesafe resolution manually yourself instead of letting 299 do the injection?! What is the usecase for this? Why do you do typesafe resolution at anything other than an injection point?
